tan()
µ key
Note: The argument is interpreted as a
degree, gradian or radian angle, according
to the current angle mode. You can use°,
g
or
r
to override the angle mode setting
temporarily.
In Gradian angle mode:
In Radian angle mode:
tan(squareMatrix1) ⇒ squareMatrix
Returns the matrix tangent of
squareMatrix1. This is not the same as
calculating the tangent of each element.
For information about the calculation
method, refer to cos().
squareMatrix1 must be diagonalizable. The
result always contains floating-point
numbers.
In Radian angle mode:
tan⁻¹()
µ key
tan⁻¹(Expr1) ⇒ expression
tan⁻¹(List1) ⇒ list
tan⁻¹(Expr1) returns the angle whose
tangent is Expr1 as an expression.
tan⁻¹(List1) returns a list of the inverse
tangents of each element of List1.
Note: The result is returned as a degree,
gradian or radian angle, according to the
current angle mode setting.
Note: You can insert this function from the
keyboard by typing arctan(...).
In Degree angle mode:
In Gradian angle mode:
In Radian angle mode:
tan⁻¹(squareMatrix1) ⇒ squareMatrix
In Radian angle mode:
